Ŭiwang's air quality reflects the flat Gyeonggi-do southwestern Seoul metropolitan corridor position adjacent to Anyang, with vehicle traffic on surrounding roads and the manufacturing, residential, and logistics character contributing local sources. Seasonal Chinese dust transport elevates PM10 during spring yellow dust episodes, while the broader Seoul metropolitan regional background maintains moderate to elevated South Korean metropolitan southwestern suburban readings throughout the year.

When is air pollution at its worst in Ŭiwang?
Ŭiwang usually sees its poorest air quality when vehicle traffic, textile and manufacturing operations, together with port and shipping activity coincide with periods when dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. These episodes tend to cluster in spring and autumn.
Are air quality levels in Ŭiwang based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
